CLOSURE FOR CHURNS.

SPECIFICATION forming part of Letters Patent No. 386,106, dated J'uly 17, 1888.

(No model.)

To all whom it may concern,.-

Be it known that I, ELisrLi P. BRYDEN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented a certain new anduseful Improvement in Closures for Revolving Barrel- Chur-ns, of which the lfollowing is a specication.

The object of this invention is to provide an improved means 0f securing covers to barrelchurns; and it consists of certain new and useful constructions and combinations of parts, hereinafter described, and pointed ont in the claims.

Referring to the accompanying drawings, which form a part of this specification, Figure l is a plan view of my improved churn-cover. Fig. 2 is a view of a vertical section of the same through the dotted line X X of Fig. l. Figs.' 3 and 4 are isometric views in det-ail of portions of the churn-cover shown in Figs. l and 2.

Like letters of reference indicate corresponding parts throughout the several views.

A is aring-head,having the periphery thereof beveled to adapt the same to enter the croze of a churn. (Not shown.)

A is an annular' flange projecting from the upper side of the ring-head A, which has a circular opening therein of the same diameter as the inside of the annular flange A.

A3 represents studs projecting from the upper side of the ring-head A,and provided with outwardly-projecting retaining-lugs A The parts just described are immovable and preferably integral.

B is a disk-head and forms the basis of the cover ofthe churn.

B is a semi-rectangular groove in the periphery of the disk-head B, containing cork or other suitable elastic packing, B2, which engageswith the annular flange Aof theringhead A.

B3 is a metallic casing,that entirely incloses the periphery and upper peripheral angle of the disk-head B.

B4 represents lower rock -shaft bearings, which project upward from the casing B3,and are preferably integral therewith.

Gis a ratch, hinge-jointed upon the pint-le C, between the lugs C2, and actuated by means of the spring C3, which is coiled aboutthe spur 0*, both spring and spur being contained in a recess (not shown) in the top of the diskhead B.

D represents rock-shafts provided with outwardly-projecting cams D, adapted to engage with the retaining-lugs A4 of the studs A3, and the inwardly-projecting detents D2, arranged and adapted to engage endwise with the ratches C. The rock -shafts D are mounted in the bearings B", and are prevented from moving whenever the rock-shafts are rocked by means of the shoulders D3. The rock-shafts D are retained in the bearings B* by means of the npperrock-shaft bearings, E, which are secured to the disk-head B and furnish supports for the lugs C2, being integral with the same.

After the cover has been placed over the opening A2 in the ring-head, turn the former until the cams Dpass under the lugs A". Then press the detents Dlz downward along the ratches C, as indicated by the dotted lines X', until the packing B2 ofthe cover forms a tight joint with the iiange A of the ring-head A. W'hen it is desired to remove the cover, press back the ratches C, as indicated by the dotted lines X2, and raise the detents D2. Afterward disengage the cams D' from the lugs A4 by turning the cover until the cams pass from under the same.

I claiml. In combination, the disk head, the ratches, the rock-shafts provided with outwardly -projecting cams adapted to engage with retaining-lugs projecting from the end of a churn, and inwardly-projecting detents arranged and adapted to engage endwise with the ratchcs, and suitable bearings for attaching and supporting the same in operative posit-ion and relation.

2. In combination, the ring-head adapted to be peripherally seated in the Croze of a churn and provided with upwardly-projecting studs, the latter being furnished with reupper rock-shaft bearing mounted thereon, the peripheral casing of the disk-head having` lower rock-shaft bearings projecting upward therefrom, and the rock-shafts provided with outwardly-projecting cams adapted to engage with said retaining-lugs, and inwardly-projecting detents arranged and adapted to engage with said ratches, substantially as described, and for the purpose set forth.
